    Abstract: A transfer case comprises a primary output shaft, and a secondary output shaft selectively coupleable to the primary output shaft with a plate clutch to transfer torque therebetween. The plate clutch includes a housing, a plurality of interleaved plates that are engaged alternatingly with the primary output shaft and the housing to rotate therewith, and an apply plate non-selectively coupled to the primary output shaft to rotate therewith. The apply plate is moveable axially along the primary output shaft into a first configuration in which the apply plate is positively coupled to the housing to rotate therewith, a second configuration in which the apply plate rotates independent of the housing, and a third configuration in which the apply plate compresses the interleaved plates to form a friction coupling between the primary output shaft and the housing.

    Abstract: A transfer case includes a primary output shaft, and a secondary output selectively coupleable to the primary output shaft with a secondary torque transfer mechanism. The secondary torque transfer mechanism comprises a plate clutch and a locking sleeve. The plate clutch includes a housing coupled to the secondary output shaft, a plurality of interleaved plates alternatingly coupled to the primary output shaft and the housing, and an apply plate coupled to the primary output shaft and being configured to compress the interleaved plates to selectively form a friction coupling between the primary output shaft and the secondary output shaft. The locking sleeve is non-selectively coupled to one of the housing or the apply plate to rotate therewith, and is selectively coupleable to the other of the housing or the apply plate to form a positive coupling between the primary output shaft and the secondary output shaft.

    Abstract: A transfer case includes primary and secondary output shafts, along with a secondary torque transfer mechanism and a locking mechanism, which are configured to selectively couple the primary and secondary output shafts. The secondary torque transfer mechanism comprises a sprocket coupled to the secondary output shaft, and a plate clutch coupled to the sprocket to selectively form a friction coupling with the primary output shaft. The locking mechanism selectively couples the primary output shaft to the sprocket, and includes a locking sleeve and an actuator that moves the locking sleeve between a first position and a second position. In the first position, the locking sleeve forms a first splined connection with the primary output shaft and forms a second splined connection with the sprocket. In the second position, the locking sleeve forms the first splined connection with the primary output shaft and forms a second splined connection with the sprocket.
